9902.11.79 - Strips wholly of expanded poly(tetrafluoroethylene) (PTFE) (CAS No. 9002-84-0), noncellular, with adhesive backing, of a thickness greater than 3 mm but not over 30 mm, presented rolled in spools, certified by the importer as having a tensile strength of 24.1 MPa (3,500 psi) or higher per American Society for Testing and Materials (ASTM) F-152 (provided for in subheading 3916.90.50)

Overview
This HTS category, 9902.11.79, specifically classifies strips made entirely of expanded poly(tetrafluoroethylene) (PTFE). These strips are characterized by being noncellular, possessing an adhesive backing, and having a thickness ranging from greater than 3 mm up to 30 mm. Crucially, they must be presented rolled on spools and certified by the importer to meet a minimum tensile strength of 24.1 MPa (3,500 psi) as determined by ASTM F-152. This detailed specification ensures precise identification of a particular type of PTFE material intended for specialized applications.
While the HTS system contains numerous categories for various materials and manufactured goods, this particular classification resides within Chapter 99, which is reserved for temporary legislation and special provisions. This means its primary function is to track imports under specific trade agreements or temporary modifications. Unlike broader categories that might cover general plastics or sheeting, this code targets a highly specific product based on its material, form, dimensions, and performance criteria. The reference to subheading 3916.90.50 within its description indicates its relationship to a more general classification for plastic articles of this nature, highlighting the temporary or special nature of this 9902 code.
As a leaf node within the HTS structure, HTS code 9902.11.79 has no further subdivisions. Its specificity means that any variation in the material's thickness, tensile strength, or its method of presentation (e.g., not rolled on spools, or lacking the required certification) would likely result in classification under a different HTS code, potentially within Chapter 39 if it doesn't fall under another temporary provision. The importer bears the responsibility of ensuring all stated criteria are met for correct classification under this unique code.
